Narrative:
Location: going direct nepta over gulf. Going direct nepta we asked for a right deviation due to WX. ATC asked how far to the right we needed to go. We responded 15 mi. ATC said ok. Shortly thereafter, after deviating no more than 3-5 mi right off course we were told to squawk 7700 because we were within 2 mi of active military airspace. We set 7700 and turned back to the left. No emergency was declared. No further communication took place between us and ATC regarding the event. Supplemental information from acn 442892: we had clearance to deviate to the north of J86 around WX and go direct nepta when able. A little later ATC advised us the warning area was 2 mi north and told us to squawk 7700. We were in a turn back to nepta at the time. Shortly after the completion of the turn ATC retuned us to our original squawk.
